Abstract In recent years, coreless axial‐flux permanent‐magnet (AFPM) machines have been gaining attention. Being coreless, these machines do not experience eddy current (hence hysteresis losses) and has lower cogging torque leading to higher eff

18th International Conference and Exhibition on Electricity Distribution (CIRED 2005).
A complete modelling and numerical simulation of a system comprising a separately excited d.c. motor fed from a single-phase, single-way rectifier are presented in this paper. The strategy of this approach is based on the cascade combination of a dio

Eighth IEE International Conference on Developments in Power System Protection.
The continuous growth of electrical energy demand is resulting in a corresponding increase in the short-circuit current in power networks. Several solutions have been implemented, including the use of fault current limiters, in order to reduce circui
